NOTE
The use of these wake up events from an ACPI state requires an operating system that provides full
ACPI support. In addition, software, drivers, and peripherals must fully support ACPI wake
events.
✏
NOTE
Wake up from PS/2 mouse is peripheral, operating system, and driver dependent; it is not a board-
level feature.
1.15.1.2.3 Plug and Play
In addition to power management, ACPI provides controls and information so that the operating
system can facilitate Plug and Play device enumeration and configuration. ACPI is used only to
enumerate and configure D815EEA2 and D815EPEA2 board devices that do not have other
hardware standards for enumeration and configuration. PCI devices on the D815EEA2 and
D815EPEA2 boards, for example, are not enumerated by ACPI.
